Battery reconditioner



April 7, 1936- L, M. SIEMON BATTERY REQO NDITIONER Filed July 9, 1935 Patented Apr. 7, 1936 UNITED STATES PATENT OFFICE 2,036,547 BATTERY anooxnmonm Lester M. Siemon, Woodmont, Conn. Application July 9, 1935, Serial No. 30,463 1 Claim. ((31. 171-314) This invention relates to a battery reconditioning device and is intended primarily to be installed or attached to and operated by the electrical system or storage battery of an automobile or other vehicle, for reconditioning the dry cells of flash lights and the like, although it may be employed for other purposes and operated from other sources of electrical current.

In the use of flash lights by electricians, linemen, meter readers etc., it is found that theory cells soon become run down and often have to be replaced after a few hours use, which necessitates a return to the shop or oifice for a new supply or the carrying of extra cells.

.To overcome this, I have devised a revlver, that can be readily attached to the mechanios automobile and. which will revive one set of dry cells while he is using the other set, as it only requires a short time to recondition dry cells to give them many additional hours oi service, and ,the operation may be repeated several times.

The object of the invention is to provide a coinpact, simple, durable and emcient device for this purpose and one that may readily be plugged into a dash light socket on the instrument hoard of an automobile or other vehicle.

Another object of the invention is to provide in a device of this kind means whereby the condi tioning rate may be regulated.

Another object of the invention is to provide a device of this kind in which one or more dry cells may be inserted therein and revived from. any automobile electric circuit or storage hat tery by the use oi the proper capacity of candle power bulbs placed in the device to act as re-= sisters.

Another object of the device is to provide means whereby dry cells of larger capacity may be attached to the binding posts for recharging from the current derived from the 6-8 volt sy tern of the automobile.

smother object or the invention is toprovide means for attaching the device to the automobile or other ohject.

With these and other objects in view, my invention consists in certain novel construction and combination of parts as will hereinaiterhe fully described and claimed and further illustrated in the accompanying drawing which forms a hereof and in which like figures of reference refer to corresponding parts in all of the views and it is understood that slight changes maybe made without departing from the spirit of the invention.

In the drawing;

' second conductor it Figure l is a perspective view of the device.

Figure 2 is a bottom view, partly in section toshow the construction and arrangement of the parts. I

As herewith shown and described, the device 5 is composed of a box-shaped casing it of insulating material and within which is molded or secured by the screws it, the two electrical conductor bars l2 and it; one of the ends it of which extends through the side of the casing i0 10 and is threaded as at 515 for the locking nut. l6 and the binding nuts ll, which provide terminals which may be connected to a storage battery or other current supply of greater capacity than that or the dry cells to be revived.

To the conductor bar i2 is attached by the screw or other means, one end of a conductor it which is mounted in the casing ill by the screw 2t which also acts as a binding screw.

In aligned relation to the conductor is is a so secured to the casing it by the screw and the screw 23 which also acts as a binding screw.

These conductors l2, l3, l9 and 2t are supplied with direct electrical current by a cable 23, 2d

of which enters the casing ill through the o ning 25 therein and its wires 26 and 211 attached to the conductors to and 2G by the screws 23; the other end oi said cable 2 9 having a standard plug it for attachment to the 3% regul socket on the automobile dash.

Within the side oi the casing it and in electrical contact with the conductor 53, is mounted a tubular huih socket is oi the usual type having in the inner end thereoi an insulating plug 39 35 carrying a contact plunger M which contacts with both the end oi the conductor El and with the center contact oi the light bulb 33 bulbs of different voltages being used to regulate the charging the circuit being completed by the {w side the hull: base and the socket For detachahly and removahly retaining the dry cells 34 within'the casing it during their reconditioning, there are provided the contact springs which have one of their ends secured to the conductor i3 and their free ends in contact with the bottom of the dry cells 3d; while the contact on the upper end oi the dry cells 3 1 is held in irictional contact with the conductor Iii. by the action of said springs.

Having thus described my invention, what I claim as new and desire to secure by letters Patent, is:

in a dry cell reconditioner oi the class described, the combination with a box-shaped casing of w insulating material, a pair oi parallel electrical conductors mounted within the sides of said casing in opposed relation to each other, binding posts formed on one end of each of said conductors and projecting through the side or said ca a pair of electrical terminals mounted I within a top or said casing and insulated from each other, one or said terminals connected to one 01 said conductors, and both of said ter- 10 minals connected to an electrical current supply,

an electrical lighting bulb and bulb socket mounted in the side of said casing the central contact of the socket connected to the second terminal and the other contact of the socket connected to the second conductor for completing the electrical circuit between the second terminal and the second conductor, and a pair of spring contacts each having one end connected to the second conductor for retaining a dry cell in contact with both or said conductors.
